In NC manufacturing of curve contours, the circular interpolation is widely used. It hasn't been completely solved how to determine the parameters of circular arcs according to desired interpolation accuracy and how to make the arc number least. In this paper, a simple and convenient interpolation algorithm for involute contours, which are widely used in the industry, is proposed. The method is based on the principle of the best approximation and has two features : (1) The interpolation error is uniform and smooth, and agrees with the specified value ; (2) The parameters of the circular arcs are determined dependent on the desired interpolation accuracy and the arc number is least. As an application example, the interpolation results for the contour of an invlute scroll used in the vaccum pump are shown.
